TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed September 19, 1917. Serial No. 192,051.

To all whom it may concern:

Be it known that I, WALTER FENTON, a subject of the King of Great Britain, rcsiding at 2 Adria road, Didsbury, Manchester, in the county of Lancaster, England, have invented new and useful Improvements in "ype-lVriting Machines, of which the following is a specification.

My invention relates to improvements in lo type Writing machines and consists essentially of an improved carriage or paper support designed primarily to give the following variety of copies, simultaneously with the original typing of a letter, document or other matter, and without removing either the original or copy from the machine eX- cept in cases of substitution, as under the fourth head, when a fresh original would have to be inserted:

1. A copy of the Whole or of a selected part or parts of the original.

2. Such copy in similar, condensed or extended spacing as compared with the original.

3. Such copy in similar, reverse or varied order as compared with the original.

4. A summary or list on one sheet of the essential or selected particulars of numerous originals and in any order.

5. Duplicates of the original or copy or both can be obtained in all cases.

My improved carriage may be applied to any suitable type of existing type writer nearly all the ordinary parts being retained 5 as usually made except the platen roller,

which is herein shown as of reduced diameter for compactness.

I illustrate my improved carriage in the accompanying sheet of diagrammatic drawings in which Figure 1 is a front elevation of my improved carriage.

Fi s. 2 and 3 are cross sectional elevations showlng the platen bar and second carrier intwo different positions.

Figs. 4 and 5 and 6 are views of details.

Fig. 7 shows another method of driving the small platen roller B.

The improved paper-carriage or sup ortconsists of two work-sheet carriers, of w ich N o. 1 comprises two sheetiding rollers D and E supported paralle to each other between and at right angles to two brackets F fixed on or forming part of a main frame or carriage connected to or controlled by the usual escapement mechanism of the machine. The roller D is preferably hollow and its pivotal extremities pass through and extend beyond the brackets F so that milled disks X or knobs or gearing for rotating the same may be secured thereon. The roller E (which might be termed a. guide bar for the sheet) may be solid and its pivotal extremities are journalcd in the brackets F, consequently both rollers D and E are capable of separate rotary motion for controllin the position and line-feeding movement of 518 main sheet a, and the roller E may be furnished with a milled disk 10 at one or both ends to facilitate its rotation. This sheet carrier No. 1 is so arranged that the most forward part of the roller D is vertically above, and the most forward part of the roller E is vertically under, the typing point of the machine. Carrier No. 2 for the work-sheet which is to receive the carbon impressions, comprises preferably two rollers A and B placed parallel to each other, and to the rollers D and E, and connected to each other b an endless band Y extending practically t e full length of the rollers A and B. The endless band Y might be dispensed with and the impression roller or platen B driven merely by the frictional contact of the movin paper or other copy sheet I; from the rol or A, contact being maintained by pressure rollers 11 in the usual Way, Fig. 7. The carrier No. 2 also comprises a metal platen bar C preferably faced with rubber or other suitable material, and two elevating and depressing levers G for raisin and lowering the front roller B and the platen bar G into or from the printing positions indicated in Figsfi2 and 3 respectively. The roller A is preferably hollow and its pivotal extremities pass through and extend beyond the brackets F so that milled disks X" or knobs or gearing for rotating the same may be secured thereon, for feeding the work-sheet b. Each sheet may thus be fed independently ofthe other.

On these pivotal extremities of the roller A beyond the brackets F are fulcrumed the twoelevating and depressing levers G which project forward and support the ends of the roller. B and platen bar C, the latter being placed above the roller T3, and the parts C and (l forming a frame hinged to the main frame or carriage brackets I The parts of this sheet carrier No. 2 are so arranged that the roller A can be rotated by means of the milled heads 4" or equivalents, and this rotary motion is connnunieated by means of the endless band Y to the revoluble platen or roller B, and the roller 1.) and the platen bar t. can be raised or lowered as required into the two positions shown In Figs. 2 and 15 b i the elevation or depression of the levers (x, so as to bring the impression po nt on the roller B or the platen bar C immediately behind the typing point of the machine.

In operation a sheet of paper, a to receive the inked type impressions and become the original, is placed in the carrier No. l by passing it forward under the roller E then upward in a vertical plane and backward over the roller 1), tension springs or clips or any suitable known device 11% being employed to guide and keep the paper a stretched between the rollers l and E as shown in Figs. 1-3 and 3.

A second sheet of )tLPUl' t) to receive the carbon impressions o the types and become the copy, together with a sheet of carbon paper superimposed upon it in the well known manner, is placed in the carrier No. 2 by passing it forward under the roller A, up around the impression roller or platen B and backward over the roller A so that the copy sheet b is in contact with the outer side of the endless band Y and is stretched and maintained in position by any suitable tensioning device.

Alternatively, the carbon paper may be placed behind and run with the original on the rollers of N o, 1 carrier.

To type the original sheet and at the same time to obtain a carbon impression on the copy sheet it is necessary to elevate the roller B and the platen bar C which causes the original sheet and the copy sheet with the earion paper inserted between them to be presented in successive contact at and Inediately behind the typing point of the type writer so that on the type keys being str'pck the types 13 Will imprint characters on the original sheet a and produce carbon impressions on the cop sheet 6.

To type on the original sheet a without giving a carbon impression on the copy sheet 6 it is necessary by means of the levers G to depress the roller B and the platen bar C, which causes the carbon sheet and copy sheet Z) to be removed from contact; with the original sheet a and the platen bar C to be brought into contact with the original sheet a immediately behind the tvpin point of the type writer. The laten bar 5 then provides the necessary so idity behind the original sheet a so that on a type key beihg struck the platen bar C will enable 2.

To obtain on one copy sheet a summary of particulars ext ltttttetl from nulneronsoriginals, it is necessary to retain the copy sheet in the carrier No. 2 While the various originals are passed through the sheet. carrier No. l, elevating the roller ll and the platen bar only during the periods in which the selected particulars are being typed on each original.

To obtain duplicate of either the original or copy itv is necessary to insert in the particular carrier and behind the original sheet or copy sheet an additional sheet of paper on Which is superimposed a carbon sheet in the manner commonly employed at present.

It will be readily understood that the details may be varied or modified without departing from the essential characteristic fea ture of the invention which consists in the construction and application of an improved i-arriage consisting of two carriers co-acting to enable the impression of the type to be varied as hereinbefore stated.

hat I claim and desire to secure by Letters Patent of the United States is:--

1. In a type writing machine, the combination of two sheetcontrolling or guiding rollers, an impression roller, a platennbar, means for rotating the impression roller, and means for moving the impression roller and the platen bar into and out of the typing" position.

2. In a, type writing machine, the combination of two sheet-carriers, of which one carrier comprises tworollers for controlling.

the original sheet, and the second carrier com- Htl till
